This paper simulates the satellite-earth link channel of SGIN based on the simulation environment of OMNeT++. We set up the model of space-ground network and satellite-earth link channel. The satellite-earth link channel includes two main parts, one part is the free space channel that ranges from the satellites to the aerosphere and the other part is the channel that ranges from aerosphere to the ground terminals. According to the ITU Recommendations, we simulate the satellite-earth link channel of the SGIN, from the results of the simulation. We analyze the satellite-earth link channel attenuation, obtaining the packet delay and packet arrival rate of the SGIN as well. more »

We apply the traditional time-expanded graph to model the data acquisition of small satellite network so that we can formulate the data acquisition into a multi-commodity concurrent flow optimization problem (MCFP) aiming at maximizing the throughput. We use an approximation method to accelerate the solution for MCFP and make global optimization of routing between satellite network nodes. After the quantitative comparison between our MCFP algorithm and general augmented path maximum flow algorithm and exploring the detail of the algorithm, we verify the approximation algorithm’s reasonable selection of routing optimization in small satellite network node communication. more »

The trend is evolving into Ultra Dense Network (UDN) architecture which is covered by cellular of irregular complex structure. In UDN, the spatial distribution of the base station plays an important role in the interference and performance evaluation of the whole cellular network, and the concept of green communication has also been put on agenda. In this paper, stochastic geometry theory is used to model UDN and to analyze the key performance of interference and wireless network. Moreover, a green communication strategy called TRSC is proposed, which is aimed at saving energy and reducing the signal interference among cells to a certain extent. more »

In the multi-user MIMO system, BD-MMSE-VP coding algorithm is proposed to improve the BER performance of the system by using the MMSE criterion to optimize the perturbation vector, and the system uses QR technique to decompose BD channel matrix. Simulation results verify the effective of the proposed precoding algorithm. more »

Health insurance can contribute to the resolution of some of these issues but insurers need to transition from simple “Payers” to “Players” in order to achieve that. They need to become points of reference on which the customer and the health care system can count on. This is possible and is strictly related to connected insurance and in particular to wearables and devices that are able to gather vital data from patients and share them with the care givers. more »

While technology needs to become more and more invisible to provide smart support, novel forms of user experience and multimodal interaction need to be devised to enable fluid, intuitive and appealing transitions between the physical and digital world. This journal seeks contributions from leading experts and visionary thinkers in industry and research, about the principles, interaction paradigms, methods and applications that best can drive the future design of Ambient Systems and their human-centred, situated interfaces. Relevant topics covered by this journal concern: * Methods and tools for the development of Pervasive Environmental infrastructure * Design of highly immersive contents for Ambient Media * Trustful mechanisms for context awareness, social sensing and inference * AIterative design and evaluation studies of multimodal interfaces * Adaptive and personalized solutions for ambient intelligence * Embodied agents and affective interfaces * Personal, social, safety and ethical issues raised by Ambient system applications, such as Domotics, Ambient Assisted Living, Pervasive Edutainment Environments. more »
